Azure Container App

Checklist de Seguranca

Antes de gerar IaC, verificar:

• Secrets via Key Vault / Secrets Manager (nunca hardcoded)
• Network isolation (VNets/​VPCs com subnets privadas)
• TLS everywhere (HTTPS, encrypted connections)
• Least privilege RBAC (roles minimas necessarias)
• Audit logging habilitado
• Encryption at rest (databases, storage)
• Private endpoints onde possivel
• Backup configurado
• Tags de custo aplicadas

Integracao com SDLC

Workflow de Deploy

deploy_workflow:
  1_plan:
    - terraform init
    - terraform plan -out=tfplan
    - Revisar plan

  2_apply_staging:
    - terraform apply tfplan
    - Verificar deploy
    - Smoke tests

  3_apply_production:
    - Aprovacao humana
    - terraform apply tfplan
    - Monitorar metricas
    - Rollback se necessario
